000 AGXX40 KNHC 211934 MIMATS Marine Weather Discussion NWS National Hurricane Center Miami FL 234 PM EST Mon Jan 21 2019 Marine Weather Discussion for the Gulf of Mexico, Caribbean Sea, and Tropical North Atlantic from 07N to 19N between 55W and 64W and the Southwest North Atlantic including the Bahamas ...GULF OF MEXICO... Strong high pressure ridging S over the Gulf from the central United States will shift E toward Cape Hatteras as low pressure deepens over the southern Plains. This will allow strong SE to S return flow to develop over the western Gulf of Mexico by Tue morning and the remainder of the basin by Tue night. Another strong cold front is expected to enter the NW Gulf on Wed and produce gale force NW to N winds over the far western Gulf from S Texas to the coast of Mexico near Veracruz. This front will reach from near the NE Gulf to the Yucatan Peninsula early Thu, then weaken as it exits the SE Gulf Thu night. ...CARIBBEAN SEA AND TROPICAL N ATLANTIC FROM 07N TO 19N BETWEEN 55W AND 64W... Fresh to strong trade winds will continue over the south-central Caribbean through Wed night, and increase to at or near gale force along the coast of Colombia each night through Thu night. Moderate to locally fresh trade winds will prevail elsewhere. A strong cold front extends across the NW Caribbean from SE Cuba to NE Honduras near 15.5N84W. The front will stall today and begin to weaken then drift north from Cuba westward Tue morning and night. Strong high pres building over the western Atlc will increase the pressure gradient over the basin Tue through Fri. This will result in strong trades over most of the eastern and central Caribbean. Strong offshore gap winds will affect the lee of Cuba, and also blow through the Mona and Windward passages, especially on Wed and Thu. ...SW N ATLANTIC INCLUDING THE BAHAMAS... A strong cold front extends from 31N65W to the SE Bahamas near 23N74W to eastern Cuba near 21N76W. The front will continue SE and stall from N of Puerto Rico to near the Windward Passage by Wed evening. Strong winds will develop between the front and 25N on Tue as strong high pressure builds north of the front. These winds will persist until Thu as the strong high following the front slowly shifts E over the western Atlc north of the area. Another strong cold front will move off the Florida coast on Thu afternoon. Gales will be possible along the front N of 30N. The front will reach from near 31N70W to the central Bahamas and to central Cuba Fri afternoon, then from near 31N69W to the SE Bahamas and eastern Cuba Fri night. Strong NW to N winds and building seas will follow in the wake of the front. $$ .WARNINGS...Any changes impacting coastal NWS offices will be coordinated through AWIPS II Collaboration Chat, or by telephone: .GULF OF MEXICO... .GMZ011...NW GULF INCLUDING STETSON BANK...
